Title: Method and apparatus for purifying effluent
IPC: B01D33/04
Filed: 1971-05-25
Abstract: 1381718 Effluent purification SWALESEDGE Ltd 25 May 1972 [25 May 1971] 17055/71 Heading C1C A method of purifying effluent comprises removing coarse solids from the effluent, feeding the liquid so-treated to at least one aeration tank, circulating liquid from the aeration tank to at least one biological filter and back to at least one aeration tank, and separating suspended solids from liquid removed from the aeration tank by electrolytic flotation. The method may be carried out in the apparatus illustrated in Fig. 2. Effluent enters day intake tank 16 which is provided with an auger 26 which agitates the effluent thereby keeping solids in suspension. This effluent is fed to a fibre stripper 28 and thence to moat compartment 12 wherein the effluent is aerated and circulated by means of rotor 26. Effluent is then pumped to the distribution tank 20. This tank allows equal distribution of effluent to the biological filters 14. The effluent is then fed back to moat compartment 12. This circulation of effluent may be carried out continuously or on a time basis. This mode of operation is interrupted by operation of the motorized valve V1 which passes effluent from the distribution tank 20 to the electrolytic flotation compartment 18. In this compartment, electrodes 36 and 38 cause an electrolytic flotation process and hence separation of suspended solids. Clarified effluent is fed from this compartment via a tapping above the electrodes to tanks T1 and T2 for further clarification. Top floating sludge may be discharged from the electrolytic flotation compartment via conduit 37 to day intake tank 16. Sludge from the base of the compartment 18 may be discharged into a sludge dewatering tank 24, and thence discharged to the outside via valve V5, surplus liquid being drained via pipe 37 to day intake tank 16. Water may be admitted into the tank 16 by valve V4 so as to maintain the liquid level in this tank.

Abstract: 596,079. Sewing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). July 18, 1945, No. 18357. [Class 112] Lock stitching with barbed needles.-In a boot sewing - machine with a take-up below the work, in which a thread finger pulls off thread during the descent of the needle to avoid the need for the needle to draw thread while ascending through the work and in which a tension device is provided between the takeup and the work to prevent slackness of the thread while the takeup is giving, up thread, this tension device provides for automatic reduction of the tension when the thread is being taken up and is actuated to relieve the tension while the needle is rising through the work so that the length of thread pulled off is not partially drawn back by the tension on the thread. Except in respect of the tension device, the machine described is similar to that of Specification 532,026 having a thread finger 8, looper 6, and rotary-arm take-up 4, the taket-up being housed in a casing formed by a flanged disc 14 and a cover 16 hinged at 18. The tension device comprises a thin plate 22 arranged in a recess in the flange 14 of the take-up casing, guided at one end by a lateral slotted lug engaging a pin 28 and at the other by a notch engaging a pin 29, and pressed towards the cover 16 by two spring plungers 24 ; the thread is pressed by the plate 22 against a co-operating surface on the cover 16 (no threading of the device thus being required) and its movement along the plate 22 as the take-up arm rotates produces the automatic variation of tension between the two phases of the take-up action. The relief of tension during part of the giving-up phase is produced by engagement of the take-up arm 4 with a cam lug 44 on a spring-pressed arm 37 pivoted at 38 in a recess in the base of the casing 14 ; an extension of the lug 44 carries a pin 48 which is notched to receive the end of the plate 22, and thus when the lug 44 is depressed the plate 22 is drawn away from the casing cover 16 against the spring plunger 24. U.S.A. Specification 2,350,995 also is referred to.
